arm. If it is more convenient, the rudder

reference unit may be mounted upside

down (label downwards), but if this is
done, the red and green wires must be
reversed in the connector unit.

It is important to ensure that

dimensions 

and B (fig. 11) are the same

at both points and that when the rudder
is amidships the unit arm is opposite the

cable gland and makes an angle of 
with the connecting bar.

Installation Precautions

Correct installation of the course
computer and 

 compass is vital to

the successful performance of the

precautions must be heeded if poor
performance or even failure of the
autopilot is to be avoided.

2.1.4 Rudder Reference

Transducer

The rudder reference unit must be

mounted on a suitable base adjacent to
the rudder stock (Fig. 10) using the self

tapping screws provided. The base height

must ensure correct vertical alignment of

TILLER

Having selected a suitable position

(Fig. 

 the interconnecting link A may

be cut to length and the linkage fastened

ensuring that the locking nuts 

B are

secure. The tiller arm should be tapped

M6 to a depth of 

 

 6in) or

through drilled to accept the ball joint

supplied. The rudder should then be

moved from side to side to ensure the
linkage is free from any obstruction,

The remote control socket is pre-wired
with the interconnecting cable. A 

 diameter hole should be bored

through the mounting panel and the

socket screwed into position using the
four self tapping screws provided (Fig. 13).

Auxiliary Alarm (Cat. No. 2035)

The auxiliary alarm unit is waterproof and

may therefore be mounted in any
position. The alarm unit is supplied with a
terminal block to connect a two core

interconnection cable to the course

computer. A 

 

 hole 

bored through the mounting panel/deck

to pass through the two way connector

block and interconnecting cable (Fig. 14).

Finally, the alarm unit should be

screwed into position using the four self
tapping screws provided. A foam seal on
the alarm mounting flange will ensure a
watertight joint to the mounting surface.
